EDMUND G. GEORGE, OF SPRINGFIELD, ILLINOIS.

naivrr srmnn.

Beit known that I, EDMUND G.'Gnoncn,

I a citizen of'the United States, and residing at Springfield, in thecounty of Sangamon and State of Illinois, have invented a certain'newand useful Improvement in Lamp- Shade's, of which the following is aSpecificati'on.

jThisinvention relates to shades, dc fsignedespecially for use withincandescent lamps. and of the type having transparent or translucentsections or panels for softening the light and producing ornamental efifects.

Prior devices of this classhave contemplated the use of glass panels orsections,

j k these being objectionable, however, not only because of'the costincident to their use, but "also because ofthe fact that because of thiscost they become a permanent fixturetunadaptable forready changing ininstances where different colored light efiects are desirable, as in theinstance of certain social functions. The use of glass panels is alsoobjectionable for the. reason that they necessitate the use of heavy andexpensive frhmes 1 for holding them, and because the extreme weight ofthe resultant shade necessitates l the provision of special clampingdevices for properly attaching them in position onthe lamp.

. "Thisinvention has for its objects to overi come the objcctionslnoted,by the production ofa simple, inexpensive shade of minimum weight, whichmay be readily applied inpofully hereinafter described.

In the accompanyingdrawin s; Figure 1 1s aside elevation of an electricamp fixture equipped with a shade embodying the invention; Fig.2 is atop plan view, partly in section, the section being taken on the line2-2, Fig, 1; Fig, 3 is a vertical section taken on the line 3-3, Fig. 1,of the shade, showing the same applied to the lamp. fixture; and,

, Specification of Letters Patent.

Application filed July 12, 1915. SerialNo. 39,509.

Patented May 23, 1916.

Fig. 4 is a detail perspective view of the clamping means for holdingtheshade in place on the fixture.

Referring to the drawing, 1 designates an electric lamp socket provided,adjacent its lower end, with a peripheral flange 2, and fittedwith anincandescent lamp globe 3, these parts, which are foreign to the invention, being of the usual construction and material.

The lamp shade forming the subject matter of the invention consists of acap 4:, a

skeleton body frame 5, and transparent or translucent sections orpanels, 6, the latter being composed of heavy oiled paper, and

removably held in the frame 5 by means of downturned engaging portionsor fingers 7 at the upper end of the frame, and upturned flanges 8 atthe lower edge of the frame.

The cap portion 4, which is formed from a. single piece or blank of thinsheet metal, and in a single operation, is provided with a centralfixture receiving opening 9, a downturned marginal flange 10, and aplurality of apertures 11 arranged at diametrically opposite points, andat a suitable spaced. distance inward from the margin of the cap,

there being provided at suitable points around the opening 9 and in theoperation of forming the cap, radial tongues or fingers 12, having theirends bent upwardly and. backwardly upon themselves, thus to formspringclamping fingers for engagement with the lamp socket 1 above therib 2, as seen more clearly in Fig. 3.

The body 5, which is formed from a single blank of thin sheet metalhaving portions cut out to form sidev openings 13 through which thepaper 6 is exposed, these openings being separated by suitable webs 14,15, 16 i and 17, of which the webs 16 form the vertically disposedcorners of the frame when the blank is folded in completed rectangularform, as indicated by dotted lines in Fig. 2, it being noted that whenthus folded the meeting ends of the blank are united at one corner ofthe frame by means of tongues 18 formed on one of the Webs 16, andengaging through slotted apertures 19 formed in the adjacent Web, Whileformed on the upper edge of the blank are tongues 20 corresponding innumberto, and properly positioned for engagement through, theperforations 11, for attaching the body frame to the cap 4. In thestamping operation incident to formation of the body blank, the latteris in cised atappnopriate intervals along its upper and lower'edge s, toprovide for formation of the fingers"? and flanges 8, the metal which isto form these pests being folded inward 'ward respectively upon the websand it ror engagement with the ad- 7 jacent edges of the sheets 6, asseen more clearly in Fig. 3, it being noted that coincident with theformation of the fingers 'i' there are provided at the upper edge of thebody suitable ventiiating openings 21.

In practice, in orderfto apply the shade to the lamp fixture, the globeis removed andthe loWer e'nd of the lamp socket 3, positioned inthe'opening 9, whereupon, by up? ward pressure on the shade, the-fingerswill spring over the rib 2 and into clamping engagement with thesocketat a point above said rib, it being :Htoted, in this connection,

- that, owing to the extrteine lightness of the shade as a whole, thefingers 17. Win

quately serve for properly securing the shade in position on the lamp,the

shade is in position, the transparent or,

translucent panels 6 will appropriately soften or color the lightradiated from the lamp, and when it is desircd'to change the panels toaccord with a particular color scheme, or to vary the monotony 'incidentto the continuous use of shade ofa certain color, "the paper sheets. orpanels may be tible o In fact, it is the purpose in marketing thereadily removed and replaced by others ofa (lifi erent color, the rangeof such changes being practically indeterminate and Suscep- 'being'madewith very slight expense,

device, to provide a number of sets of panels 6 of difi'erentcolors, tobe interchanged at will. It is evident thatthe several component partsofthe shade are ofextreme simplicityin construction, and are so formedthat they may-bereadily set up in completed form for use, and further,that they are all produced from light Weight material;

sme

whereby il Slevice as a Whole maybe inexpeusively predated 2 nd maybeapplied to the lamp and prop rly supported thereon hf means of theSimplified form or g fips herein shown.

It is obvious that various changes ma be made in th dot-ails ofconstruction Witheut ,departi ng {hm the spirit of this invemtherci'bre, to be understood that ties if i thisjin-vention not to belimited to the specific GQHwtd'llQil-QQ shel Y!) sad described- Havingthus described the inyention, what is claimed is: 7

1. A lamp shade comprising frame and a cap, each of said partbrainstormed fr'rom a single sheet of materialplsaiil cap having anopening and a plurality of radial spring fingers projecting into saidopening, and means for attaching the cap to the body. 2. A lamp shadecomprising a body frame and a cap, each formed from a single sheet ofmaterial and having integral intrengaging portions for attaching the capto the body, said cap having an opening and a mate o ed spring fingers pj n i to said r pe n a 3. A lamp sheds QOmprising a body frame and acap,said body frame being formed from a single sheet of material andhaving enlarged panel openings, paper panels arranged in the body frameto cover said openings, and means on said body frame for holding thepanels in place. v
